LOS ANGELES — A 24-year-old man was charged today with attempted murder and other crimes in a string of screwdriver attacks on Metro buses.

Hector Resendez pleaded not guilty to five counts each of attempted murder and assault with a deadly weapon, along with three counts of battery.

Resendez allegedly assaulted eight passengers between June 16 and June 27, stabbing several with a screwdriver, according to the District Attorney’s Office. No motive has been disclosed.

None of the injuries was considered life-threatening, according to the District Attorney’s Office.

Resendez was arrested June 27, shortly after a stabbing occurred on a bus at Slauson Avenue and Atlantic Boulevard in Maywood. Five hours earlier, a passenger was stabbed on a bus at Figueroa Street and Avenue 26 in Cypress Park, authorities said.

The Maywood attack prompted a dragnet of the area by sheriff’s deputies, with the sheriff’s Headquarters Bureau confirming that Resendez had been arrested in connection with the attacks.
